Anatomy of Citrus

La agricultura del s. XXI debe estar basada en el conocimiento científico, y no solo en el empirismo y la experiencia, por muy amplia que ésta sea. Solo de este modo el agricultor será capaz de comprender e interpretar la adaptación de las especies al medio y favorecer la producción de frutos. A todo ello contribuye el conocimiento en Anatomía, Bioquímica, Biología, Botánica, Climatología, Edafología, Entomología, Fisiología, Genética, Patología. El primer paso para el avance en el cultivo de las plantas es conocer cómo son sus órganos y sus tejidos. Anatomía de los Cítricos describe en profundidad los órganos de estas plantas (raíz, tallo, hoja, flor, semilla y fruto) explicando cómo están organizados y cómo son sus tejidos. El texto se apoya en una selección de 161 fotografías de microscopía óptica y electrónica obtenidas en trabajos de investigación durante los últimos 35 años.Martínez Alcántara, B.; Tadeo Serrano, FR.; Mesejo Conejos, C.; Martínez Cuenca, MR.; Ruiz Valdés, M.; Reig Valor, C.; Forner Giner, MÁ....

Learning by educating: Service learning experience of oral health promotion integrated into a subject. Pilot project

Después de dos años desarrollando la metodología ApS, este proyecto estaba propuesto con la intención de integrar esta metodología en una asignatura de 5º curso del Grado de Odontología. Varios alumnos de la asignatura participaron en el proyecto, pero ante su bajo número se brindó la oportunidad al resto de cursos, para todos aquellos estudiantes que quisieran participar de forma voluntaria. Los objetivos propuestos en el proyecto fueron alcanzados con entera satisfacción.After two years developing the SL methodology, this project was proposed with the intention of integrating this methodology in a 5th year subject of the Degree in Dentistry. Several students participated in the project, but due to its low number, an opportunity was provided other students, for those who wanted to participate voluntarily. The objectives proposed in the project were successfully achieved.Depto. de Especialidades Clínicas OdontológicasFac. de OdontologíaUniversidad Complutense de Madrid. Proyectos ApSunpu

Prevalence and genotype distribution of cervical human papilomavirus infection in the pre-vaccination era: a population-based study in the Canary Islands

Objective National Spanish studies show that prevalence of cervical human papillomavirus (HPV) infection in the female population is increasingly frequent, with an overall estimate of 14% in women aged 18–65 years. The objective of this study is to know the prevalence and distribution of HPV types in the female population of the Canary Islands prior to the introduction of HPV vaccines and to investigate the associated clinical and sociodemographic factors.Methods Based on the Primary Health Care database, a sample of adult women (aged 18–65 years) of Gran Canaria (GC) and Tenerife (TF) stratified into nine age groups was carried out between 2002 and 2007. Women were contacted by postal letter and telephone call and were visited in their primary care centre. A clinical-epidemiological survey was completed and cervical samples were taken for cytological study and HPV detection. HPV prevalence and its 95% CI were estimated, and multivariate analyses were performed using logistic regression to identify factors associated with the infection.Results 6010 women participated in the study, 3847 from GC and 2163 from TF. The overall prevalence of HPV infection was 13.6% (CI 12.8%–14.5%) and 11.1% (CI 10.3%–11.9%) for high-risk types. The most frequent HPV type was 16 followed by types 51, 53, 31, 42 and 59. HPV types included in the nonavalent vaccine were detected in 54.1% of infected women. Factors associated with an increased risk of infection were: young ages (18–29 years), the number of sexual partners throughout life, not being married, being a smoker, and having had previous cervical lesions or genital warts.Conclusions It is confirmed that prevalence of HPV infection in the female population of the Canary Islands is high, but similar to that of Spain, HPV 16 being the most frequent genotype. The determinants of infection are consistent with those of other populations

Diagnostic yield of chest and thumb ECG after cryptogenic stroke, Transient ECG Assessment in Stroke Evaluation (TEASE): an observational trial

Objective In stroke survivors, atrial fibrillation (AF) is typically evaluated solely by short-term ECG monitoring in the stroke unit. Prolonged continuous ECG monitoring or insertable cardiac monitors require substantial resources. Chest and thumb ECG could provide an alternative means of AF detection, which in turn could allow prompt anticoagulation to prevent recurrent stroke. The objective of this study was to assess the yield of newly diagnosed AF during 28 days of chest and thumb ECG monitoring two times per day in cryptogenic stroke.Methods This study, Transient ECG Assessment in Stroke Evaluation, included patients who had a stroke from Region Gävleborg, Sweden, between 2017 and 2019. Patients with a recent ischaemic stroke without documented AF (or other reasons for anticoagulation) before or during ECG evaluation in the stroke unit were evaluated using the Coala Heart Monitor connected to a smartphone application for remote monitoring.Results The prespecified number of 100 patients (mean age 67.6±10.8 years; 60% men) was analysed. In nine patients (9%, number needed to screen 11) AF but no other significant atrial arrhythmias (>30 s) was diagnosed. The mean CHA2DS2-VASc score was similar among patients with AF and no AF (4.9±1.1 vs 4.3±1.3; p=0.224) and patients with AF were older (74.3±9.0 vs 66.9±10.8; p=0.049). Patients performed on average 90.1%±15.0% of scheduled transmissions.Conclusion In evaluation of cryptogenic stroke, 9% of patients had AF detected using chest and thumb ECG two times per day during 1 month. In many stroke survivors, this is a feasible approach and they will be potentially protected from recurrent stroke by anticoagulation treatment.Trial registration number NCT03301662

"Las cosas singulares de piedras, animales, plantas": la formación y el funcionamiento de la red imperial española de remesas centíficas en el Virreinato del Río de la Plata

El presente artículo acompaña el proceso de remesa de especímenes animales y vegetales de la región administrativa del Virreinato del Río de la Plata para las instituciones científicas españolas, tales como el Real Gabinete, el Real Jardín Botánico y las menageries del Retiro y de Aranjuez. El propósito fue intentar sorprender esas remesas en el exacto momento en que tales instituciones y sus redes de recolección estaban siendo creadas, buscando expli- car las lógicas que las presidían, en un momento en que se mezclaban propósitos de orden económico; la cultura de la dádiva, típica del Antiguo Régimen; con las modernas prácticas científicas que estaban en construcción
